A U-shaped wire is dipped in a soap solution, and removed. A thin soap film formed between the wire and a light slider supports a weight of `1.5xx10^(-2)N` (which includes the small weigh of the slider). The length of the slider is 30cm. What is the surface tension of the film?

A thin liquid film formed between a U-shaped wire and a light slider supports a weight of 1.5xx10^-2N (see figure). The length of the slider is 30cm and its weight negligible. The surface tension of the liquid film is

A thin liquid film formed between a U- shaped wire and a light slider supports a weight of 1.5 xx 10^(-2)N (see figure). The length of the slider is 30 cm and its weight neligible. The surfaces tension of the liquid film is :

The surface tension of a thin liquid film formed between a U shaped wire and a light slider of length 30 cm supporing a weight of 1.5xx10^(-2)N is

A wire is bent in the form of a U -shape and a slider of negligible mass is connecting the two vertical sides of the U-shape. This arrangement is dipped in a soap solution and lifted a thin soap film is formed in t he frame it supports a wegith of 2.0xx10^(-2) if the length of the slider is 40 cm whta is the surface tension of the film?

A thin film of liquid is formed in a rectangular frame of wire and a light slider supports a weight of (2.5 * 10^-2)N .The length of slider is 20cm and its weight negligible. The surface tension is liquid is

A thin soap film is formed on a U shaped wire loop having a slider (of negliglibe mass) of length 10 cm. it is found that the film can support a weight of 0.012 N, before it breaks. What is the surface tension of the film ?

If 72 xx 10^(-5) J of work is done to increase the radius of a soap bubble from 2 cm to 3 cm. What is the surface tension of the soap solution?

Fig, shown a thin film supporting a small weight = 4.5xx10^(-2)N . What is the weight supported by a film of the same liquid at the same temperature in fig. explain your answer physically. .
